WIGKLESS BURNER FOR USE IN CONNECTION WITH PETROLEUM OR OTHER LIQUID HYDROCARBONS.

Application filed March 25, 1922. Serial No. 5%,857.

To all 107mm it may concern:

Be it known that 1, PAUL Lucas, a citizen of the German Republic, and resident of 1Berlinl riedenau, Germany, have invented a certain new and useful Improved lVickless Burner for Use in Connection with Petroleum or Other Liquid Hydrocarbons.

This invention relates to a wickless burner in which petroleum or other liquid hydrocarbons may be burned.

According to this invention the burnertube extending upwards from the fuel-receptacle consists of German silver or another alloy which is a comparatively bad conductor of heat, so that the tightening between the burner tube and the fuel receptacle may be effected by the medium of a screw-threaded connecting member, simply by a disk of cork or an equivalent organic substance without any fear of this packing disk being ignited during the service.

Owing to the strong heating of the burnertube and the fuel-receptacle, the tightening of the joint between these parts could hitherton be effected only by an asbestos packing member or a metallic packing member, but both materials have proved unsatisfactory in practical service. i I

The invention ofi'ers also the further considerable advantage that the burner-tube may be grasped during the service (or l11l mediately thereafter) at its lower end and, if desired, may be turned, without any dan ger of burning ones hand, the fact being that the tightening place remainswalways cool.

Igniting a burner of the before-mentioned improved kind is effected by means of an ignition tube arranged outside of the preheating or starting bowl and containing a wick which sucks the liquid fuel from that bowl. Owing to the ignition tube being located. outside of the preheating ,or starting bowl, the material advantage is obtained that the fuel getting into the ignition tube gasifies not too quickly, and by a certain quantity of the fuel being sucked up by the wick portion within the ignition tube a certain store of fuel is accumulated which lasts for a comparatively long time and ensures the ignitibility also in this direction.

As, by the employment of the German silver tube, an easily disconnectable connection between the burner and the receptacle is brought about, it is easily possible to an change a cooking or heating burner for an lncandescence-light burner, and reversely, both burners having the same thread. In such a construction the provision is necessary that the grate, or the supporting ring respectively, be removable without any difficulty, and may also easily be reinserted. The grate or ring is, for this purpose, p1'0- vided with hinged feet which are removable together with the said grate .or ring. The lower ends of said feet are, preferably, hook-shaped, these hooks having horizontal recesses receiving portions of an annular projection formed at the fuel receptacle by a circumferential groove,

Thus, the grate or supporting ring having been put in place upon the receptacle, a downwardly directed pressure acting upon the junction places is produced whereby the stability of the upper supporting structure is warranted and the feet are securely prevented from spreading.

I am aware of a known structure for a similar purpose, having feet hinged to a supporting ring and carrying the fuel receptacle so-to-say floatingly; there are in these feet rounded recesses, the shape of which is such that they cannnot prevent the feet from spreading under the pressure produced by the supporting ring and its load.

if a cooking device constructed according to the present invention is to bechanged into an illuminating burner, the feet supporting the ring are drawn off. the fuel receptacle, the ring is removed, and the heating or cooking burner is replaced by an illuminating burner which is attached to the fuel receptacle in lieu ofsaid other burner.

In order to make my invention more clear, I refer to the accompanying drawings in which similar letters of reference denote similar parts throughout the several views, and in which Figure 1 is a vertical section through a petroleum-burner constructed according to this invention, the fuel receptacle being shown partly in side-view. Fig. 2 is a vertical section solely through the burner proper having, in this instance, a special ignition tube. Fig. 3 is a side-view of the complete burner, as shown in Fig. l but turned into a cooking or heating burner by the addition of an appropriate upper structure, as shown. Fig. 4 is a side-view of. some members of said structure, viz. one of its feet, in combination with a portion of the sup iiorting ring, to which all feet are hinged. l i is a plan of the supporting ring. and Fig. 6 shows the fuel receptacle provided with an illuminating burner instead of with a cooking or heating burner, and furnished with the other appliances a lamp requires.

The fuel receptacle 1 is provided in known manner with an air pump 2 and a filling branch 3 having a ventilatingscrew 3*. The burner tube 6 which is provided at its upper endwith the nozzle 7 consists ofGermansilver or another alloy which is a comparatively bad conductor of heat so that the-lower portion of the burner tube which is to be packed. remains @001 during the service. The burner tubeis held in place by a flanged sleeve 4!; forinii'ig a kind of cap-nut and effooting the tightening of the junction with aid of a packing ring 5 placedbetween the flange of-l and the opposite annular portion of the'top of the receptacle 1. The ring .5 consists, preferably, of cork or an equivalent substance.

The burner proper consists of a plurality ofparts which are not parts of this invention. There is a burner head '9 with air-supply apertures 8, a-basin'sha-ped annular disk 10 which is soldered to thehead 9, and a preheating or starting basin12.

In the form of construction shown in F ig. 2. the basin 12, which is attached to the lower end of a piece of tube 13 extending down from the burner head, is provided with an upwardly extending ignition-tube 14: containing a wick 15. The ignition tube is, in the example shown somewhat oblique, but itmay be perfectly vertical as well;'1t communicates with the basin 12 through an aperture 16 and ignites in known manner the gases generated within the burner and escaping through the lateral apertures of its head.

. "Referring to Figures 8, 4t and'5 in which the fuel receptacle and the burner are furnished with the means for supporting a cooking vessel, these means consist of a plurality of feet 20 which are U-shaped in transverse section as shown at 21 in Figs. 3 and 4., and are hinged at their upper ends to a ring 19 having downwardly extending lugs to which the .feet 20 are hinged by means of pins 22. The lower ends of the feet 20 form hooks 23 which engage a circumferential groove 18 provided-myths receptacle-1. Theh'o'ok-s 23 fit tightly'into the groove 18.

If. the upper structure (1.9, 20etc.) shall be removed from the receptacle and the burner, the hooks 23 are drawn out of the groove .18 and the upper structure iis collapsed by turning the feet inwards as shown in dotted lines in Fig. 4.

Referring now-to Fig.6 the cookin 13111 11- ier is heregreplaoed by an :illuminatingfiflurner also attached to a tube 6 having a nozzle, as shown. This burner has at its lower end a space 24 provided for the preheating or starting purpose. .25 are lateral apertures affording access to the space 24. The upper burner-tube proper consists, preferably, of copperand encloses a smaller tubular member 27 which communicates at its lower end with the nozzle of the tube 6, as well as with lateral apertures 26 through which air conducted to the petroleum vapor rising in the tubular member 27.

27 is a short U-shapedconnecting member between the inner space of the insertion 27 and the space between this insertion and the burner tube. A. small portion of the mixture rising in the insertion 27 escapes through the communication afforded by the piece 2 7 into that annular intermediate space and gets then downwards to apertures 27 provided in the copper burner tube. These small mixture currents are ignited and form auXilia-ryfiames. The main portion, however, of the mixture escapes at th'etop of the burner tube where there are apertures 28 for that purpose. This portion of the mixture produces the heating flame for the incandescence body which is shown in dotted lines. The lamp shade 29 is sup'portedby a ring provided with standards 30. The configuration of these latter at their lower ends practically the same as with the feet 20 of Fig. 3. i

The tube6 is provided at its lower end with a ratherbroadfiange 31 forming a kind of footfor the burner when out of use. The parts below that flange or foot are the sam as in Fig. 1.
